Arcade Validate URL in Popup

[MeleKoneya]

We have a planning cases Operations Dashboard.    On the ArcGIS Online Popup there is a link to the Applicant's Submittal.    Most of the planning cases have an associated PDF, but not all.

I would like to validate that a URL has content and does not give a 404 error.

Can this be done in an ArcGIS Online popup with Arcade and/or another method?

Thanks,

Mele

Hello Mele,

Unfortunately there isn't really a way to do this with Arcade language, as this language is primarily used for controlling the way GIS features are rendered and labeled, rather than interacting with hyperlinked content. A list of the current available Arcade functions can be found below.

There isn't really any available out-of-the-box functionality for validating URLs within an ArcGIS Online popup at this time. For a workflow like this, it may be more worthwhile to explore a workflow that involves exporting the table containing the applicant URLs from your webmap data, and running the URLs through a status checker website like the one linked below.

Bulk URL status code checker:

I hope this information helps!

Tyler,

Thanks for confirming this.   I was not able to find any examples, so I see why.

I did use a similar approach as you suggested.  I created a .NET program which validates a URL in our Enterprise Geodatabase Feature Class and updates a field if the URL is valid.   I am then using that field in Arcade. 

Thanks
